heretofore known and to provide a fastener which will hold vthe assembled papers securely, can bemanipulated easil 1s 1i ht gasf of increased thickness of the file, the locks and, nevertheless, sufficiently sti and no flan es or lips projecting .substantially above t eplane of the uppermost sheet of the file. l 1 Y Other ob'ects and advantages of the'invention wi be indicated as 1t is described in the following specification with reference to the accompanying drawin in which Fig. 1 is a sectional viewo afile illustrating the application of the improved fastener thereto; Fig. 2 is a perspective view of the fas tener';. I

Fig. 3 is a plan view of the keeper; Fig. 4 is an enlarged. transverse section on the line 4-4 of Fig. 3; p Fig. 5 is another transverse section similar to Fig. 4 4and showing modified locks and Fig. 6 is a transverse section through the device showing another modication.

Referring to the drawing, 5 indicates the base of the fastener, having 6 'formed integrally therewith and adapted to be bent as indicated and to pass through the file of papers 7. The ends of the tongues 6` reject through` perforations 8 nearfthe .eggs of a keeper 9 which rests upon the u permost paper of the file.

The keeper 9 consists of a strip of metal having two longitudinal ribs 10 von the face -orf 'upper surface thereof, the ribs being forme b pressing or otherwise forcing up the bo y of strip. `Two slidin locks 11 are mounted on the keeper 9., ese locks are metal strips slightly depressed between the ribs and having their ends'12 bent over the an'ges 13 at the sides of the keeper. The locks are preferably cut away at14, so that when they are disposed contiguously the thumb or finger-nail may be inserted to separate them and rmit movement thereof toward the ends of the keeper., The purpose of the locks is to securely hold the ends spaced tongues of the tongues Y'6 which, after ilssiiig` through the perforations 8 inlthe eeper, are bent inwardly and downwardly into the depression or groove 9 between the ribs 10. The locksywhich may be moved to either end of the keeper, can be slip ed over the ends of the tongues, and will held frictionally in adjusted position because of resilience of the tongue. If the file is relatively thin the ends of the tongues will be long and the locks may be dis osed near the center of the keeper. When t e rojecting ends of the tongues are shorter, ause will be s aced apart, each covering the end of one o the tongues. Although two locks are desirable, one ma be used especially when the files are re atively "thin or the tongues are long. l

The ribs 10 serve several purposes. As already noted, they provide a de ression or groove to receive the ends of t e ton es 6 so that the latter can be held by-the locks 11 below the plane of the up er'surface of the ribs. The tongues are t us prevented from projecting in such a way as to catch and tear papers) which may be'inserted in the file above the keeper. The ribs stien the kee er so that relativelylight metal can be usedp for the body thereof and they permit the ed es or flanges 1,3 to be close to the plane of t e uppermost 'aper of the le so that the danger of cate ing papers on the flanges is minimized. L

Another and important function of the ribs .10 is to prevent escape of the locks from the keepers. In pressing the ribs from the stri of 4metal the edges of the flanges 13 are rawn in sli htly but s the ribs do not extend to the en s 15 of the keeper these ends are somewhat flared as indicated in an exaggerated manner in Figs. 2 and 3 of the drawing. The locks 11 are applied to the ykee er after'the latter has been formed and sli e freely on the keeper between the ends 15. They cannot, however, pass over' the Hated ends.V The ends 15are, referably, slightly'ldepressed from the p ane of the body of the keeper to rest upon the uppermost paper of t e file and to facilitate movement of the locks.

In Fig. 5 of the drawing the ends 16 of the locks 17 are turned upwardly into the grooves 18 formed in the lower faceof the keeper 19 by striking up the ribs 20 thereon. As in the preceding embodiment of the invention, the ribs 20 terminate short of the ends of the keeper and consequently the ends 16 of 'the locks cannot escape from the grooves. Removal of the locks is thus prevented. 1

In Fig. 6 the flanges 13 are omitted and ribs Q1 are formed at the edges of the keeper. The ends 22 of the locks 11 are turned upwardly into the grooves 23 in the lower face of the keeper. The ribs 21 may terminate short of the endsmf the keepe as in the preceding embodiments of the.i vention.

The keeper as described affords-a secure fastening for the ends of the tongues 6 and firmly binds the bpapers in the file. The keeper can, however, be removed easily by sliding the locks to release the ton ues. The locks can be moved in theadesire direction for that purpose by slight'pressure of the thumb or finger.

Various changes can be made within the scope of the accompanying claims without departing from the invention or sacrificing an of the advantages thereof.

1. A fastener comprising a base having spaced tongues and a keeper with similarly spaced erforations to receive the tongues, longitu inal ribs on the upper face of the keeper extending continuously between the ends thereof but terminating short of the ends, a plurality of locks adapted to overlie the ends of the ton es when the latter are threaded through tel perforations and bent into the groove between the ribs, and sto s for the locks formed at the ends of t e keeper.

2. A fastener comprising a base having spaced ton es and a keeper with similarly spaced cpe orations to receive the tongues, longitu inal ribs on the upper face of the keeper extending continuously between the ends thereof but terminating short of the ends and a plurality of locks adapted to overlie the ends of the ton es when the latter are threaded throught e perforatonsf and bent into the groove between the ribs, the ends of the locks being bent over the lateral edges of the keeper and projectin into grooves formed on the underside o the keeper.

3.
